[0002] The wading ability of a vehicle is an important indicator of automobile assessment, which is related to factors such as the chassis height of the vehicle, the position of the engine air intake, and the sealing performance between the various components of the vehicle. With the increase in extreme weather, vehicles will face unexpected water accumulation during driving. When the vehicle wades, the sealing performance of the vehicle body faces severe challenges. If the sealing performance is not good, the accumulated water can easily penetrate into the vehicle, causing electrical system failures, corrosion and other problems.

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0025] In the present application, terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship of quantity, priority or sequence between these entities or operations.
[0026] Please also read Figure 1 and Figure 2 The vehicle body sealing structure provided by the utility model is now described. The vehicle body sealing structure comprises a frame 1, a foaming rubber block 4 and a hot melt flowing rubber block 2. The frame 1 is provided with a hot melt sealing area 3 and a foaming limiting groove 14 in sequence from top to bottom; the foaming rubber block 4 is arranged in the foaming limiting groove 14, and after foaming, fills the foaming filling area between the foaming limiting groove 14 and the vehicle body sheet metal 5, forming a first sealing structure 6; the hot melt flowing rubber block 2 is arranged in the hot melt sealing area 3, and after hot melting, flows to the foamed foaming rubber block 4 and fills the gap between it and the vehicle body sheet metal 5, forming a second sealing structure 7.
[0027] The vehicle body sealing structure provided by the utility model adopts a combination of foam glue and flowing glue. During electrophoresis baking, the foam glue first foams and contacts with the vehicle body sheet metal 5 to form a first sealing structure 6. The flowing glue then melts and flows to the narrow gap between the foam glue and the sheet metal under the action of gravity to serve as a second sealing structure 7, thereby realizing double sealing of the gap between the vehicle body sheet metal 5 and achieving a better sealing effect.
[0028] The hot melt flowing adhesive block 2 of the present application is also directly arranged on the upper part of the foaming limiting groove 14, and the placement area of the hot melt flowing adhesive block 2 overlaps with its hot melt sealing area 3. Therefore, after the hot melt flowing adhesive block 2 is hot-melted, it can flow directly in the hot melt sealing area without having to flow from other placement areas to the hot melt sealing area. Such a design can not only achieve a double sealing effect, but also reduce the size of the skeleton, reduce the space volume occupied by the sealing structure, and also reduce the flow time of the hot melt flowing adhesive block and unnecessary waste.
[0029] The foam rubber block 4 and the hot-melt flowing rubber block 2 used in the present application are both made of EVA material, but the difference between the two is that the foam rubber block 4 is baked and foamed, and the foaming temperature is lower than the melting temperature of the hot-melt flowing rubber block 2. The hot-melt flowing rubber block 2 is solid at room temperature, and has good fluidity when the temperature reaches the melting temperature. It can fill sharp corners, corners, angles and other areas that are difficult to fill with foam, thereby improving the sealing reliability of the entire vehicle and thus improving the wading performance of the entire vehicle.
[0030] For example, the foaming temperature of the foamed rubber block 4 is 140°C, and the melting temperature of the hot melt flowing rubber block 2 is 145-150°C; during baking, the foamed rubber block 4 and the hot melt flowing rubber block 2 begin to be heated at basically the same time. As the temperature rises, when the foaming temperature of the foamed rubber block 4 is reached, the foamed rubber block 4 foams and expands first, and quickly fills the gap between it and the body sheet metal 5; while the foamed rubber block 4 is foaming, the temperature continues to rise. When the melting temperature of the hot melt flowing rubber block 2 is reached, the hot melt flowing rubber block 2 begins to melt and begins to flow under gravity. When the hot-melt glue flows to the foamed rubber block 4, the foamed rubber block 4 just foams to the maximum volume; the hot melt flow lags behind the foaming of the foamed rubber block 4, so that the hot melt glue can cover the foamed foamed rubber block 4 when the foamed rubber block 4 just foams to the maximum volume. In this way, the hot melt glue can fill the gap that the foamed rubber block 4 does not want to fill, thereby achieving a perfect match between the two glues.
[0031] The chemical name of EVA is ethylene-vinyl acetate copolymer, which is a high molecular polymer with the molecular formula (C2H4)x.(C4H6O2)y. It is flammable and will produce carbon monoxide and carbon dioxide after combustion. It has good aging resistance, water resistance, ozone resistance and chemical stability.
[0032] EVA foam is a foam material, which is made from raw materials produced by the copolymerization of ethylene (E) and vinyl acetate (VA). The preparation process of EVA foam usually includes main materials (such as EVA and / or PE), fillers (such as calcium carbonate or talc), foaming agents and other ingredients. The ratio and addition of these ingredients can be adjusted according to the specific requirements of the product to improve the physical properties of the product.
[0033] Hot melt adhesive is a solvent-free solid adhesive made of thermoplastic resin or thermoplastic elastomer as the main component, with plasticizer, tackifying resin, antioxidant, flame retardant and filler added, which is made by melt mixing.
[0034] EVA hot melt adhesive is a solvent-free, moisture-free, 100% solid fusible polymer. It is solid at room temperature and becomes a liquid adhesive that can flow and has a certain viscosity when heated and melted to a certain degree. After melting, it is light brown translucent or white. The main component of EVA hot melt adhesive, that is, the basic resin, is made by copolymerizing ethylene and vinyl acetate under high pressure, and then mixed with tackifiers, viscosity regulators, antioxidants, etc. to make hot melt adhesive.
[0035] In some embodiments, Figure 1 and Figure 2 As shown, the hot melt sealing area 3 is provided with a support plane 12 and a guide slope 11, and the guide slope 11 is inclined in the opposite direction of the hot melt flow, so that the angle θ formed between the support plane 12 and the guide slope 11 is an obtuse angle; the hot melt flowing adhesive block 2 is supported on the support plane 12 and is close to the guide slope 11. The hot melt sealing area 3 is constructed on the skeleton 1, and the support plane 12 is constructed on the skeleton 1 to support the hot melt flowing adhesive block 2 which is solid at room temperature, and to provide a flow path for the hot melt flowing adhesive block 2 to lag behind the foaming state of the foaming adhesive block 4. The support plane 12 is located above the foaming limiting groove 14, and the molten adhesive flows to the foaming foaming adhesive block 4 under the action of gravity, and flows to fill the gap not filled by the foaming adhesive block 4.
[0036] The guide slope 11 is set at an obtuse angle θ with the support plane 12, and the shape of the hot melt flow adhesive block 2 is formed into a trapezoidal structure with a long upper bottom and a short lower bottom. Because one side of the hot melt flow adhesive block 2 is in close contact with the guide slope 11, this design has multiple functions compared to constructing a vertical limit surface perpendicular to the support plane 12. First, the center of gravity of the hot melt flow adhesive block 2 is moved backward, that is, its center of gravity is farther away from the body sheet metal 5 than the center of gravity of the rectangular hot melt flow adhesive block 2. By moving the center of gravity backward, the flow direction of the hot melt flow adhesive block 2 can be adjusted. Secondly, the flow time of the gap between the body sheet metal 5 and the frame 1 is shortened, thereby preventing the hot-melt glue block from being ahead of the time when the foam glue block 4 is completely foamed, thereby ensuring that the glue can fill the gap left after the foam glue block 4 is foamed; secondly, the backward shift of the center of gravity of the hot-melt flowing glue block 2, under the condition of the same flow distance or flow time of the hot-melt glue on the supporting plane 12, can reduce the length of the supporting plane 12 along the flow direction, thereby reducing the size of the frame 1; thirdly, the hot-melt flowing glue block 2 is attached to the guide slope 11 to form a landslide-like principle, which makes the hot-melt glue more likely to slide.
[0037] The volume a of the hot melt flowable adhesive block 2 in the solid state at room temperature is equal to the volume b of the hot melt flowable adhesive block 2 in the glue liquid state after melting. Specifically, the hot melt flowable adhesive block 2 has a trapezoidal cross section in the solid state, and the cross section after melting and solidifying at room temperature is still approximately trapezoidal. This is because part of the glue liquid will fill the gap between the body sheet metal 5 and the frame 1 and the gap after the foaming adhesive block 4 is foamed. However, since the gap between the body sheet metal 5 and the frame 1 is not too large, generally less than a few millimeters, and the volume of the gap is even smaller, it can be ignored.
[0038] In some embodiments, see Figure 1 , the angle θ between the support plane 12 and the diversion slope 11 is ≤ 135°. The smaller the obtuse angle θ is, the greater the slope of the diversion slope 11 is, and the easier it is for the hot melt to flow in a landslide. Optionally, θ is 120°, 130°, 135°, etc.
[0039] In some embodiments, see Figure 1 After the hot melt flow adhesive block 2 flows to the foam adhesive block 4, the height h1 formed on the support plane 12 is ≥3.0mm. Due to the principle of fluid flow from high to low, the gap filled by the hot melt adhesive must not be higher than the support plane 12, otherwise the gap cannot be filled and sealed; and because the adhesive will adhere to the body sheet metal 5, the skeleton 1 and the foamed foam adhesive block 4 at room temperature after hot melt flow, if there is no certain height on the support plane 12, the sealing layer formed by the hot melt flow adhesive block 2 will easily lose its function in the fatigue damage caused by repeated bumps and vibrations of the vehicle; therefore, the height of the hot melt flow adhesive block 2 after flowing needs to be limited to ensure the durable sealing performance during the long-term use of the vehicle.
[0040] In some embodiments, see Figure 1 , the hot melt flow distance e from the hot melt flow adhesive block 2 to the boundary of the support plane 12 is 3mm-5mm. When the hot melt adhesive flows to the boundary of the support plane 12, it will detach from the support plane 12 under the action of gravity and flow downward to the foamed adhesive block 4. Therefore, the limitation of the flow distance of the adhesive on the support plane 12 here is also to adjust the flow time of the adhesive when it contacts the foamed adhesive block 4, so as to avoid the adhesive directly detaching from the support plane 12 after hot melting and flowing to the unfoamed foamed adhesive block 4, thereby forming the risk of sealing failure. In short, by ensuring the flow distance and flow time of the hot melt adhesive, time is reserved for the foaming of the foamed adhesive block 4, so that the adhesive can reach the foamed adhesive block 4 just after the foaming is completed, thereby improving the hot melt adhesive to fill the foamed adhesive block 4, and improving the sealing effect of the second sealing structure 7.
[0041] It should be noted that the flow distance of the hot melt flowable adhesive block 2 on the support plane 12 after hot melting can be adjusted according to the volume of the hot melt flowable adhesive block 2, the foaming volume of the foaming adhesive block 4, etc., and the distance can be appropriately increased or decreased.
[0042] In some embodiments, see Figure 1 The foaming limit groove 14 has an upper limit portion 13 and a lower limit portion 15. The upper surface of the upper limit portion 13 constitutes the support plane 12 of the hot melt flow adhesive block 2. The distance from the upper limit portion 13 to the body sheet metal 5 is smaller than the distance from the lower limit portion 15 to the body sheet metal 5. The upper boundary of the foamed adhesive block 4 after foaming is lower than the support plane 12. The foaming limit groove 14 provided on the frame 1, on the one hand, provides a containing space for the foamed adhesive block 4, and on the other hand, guides its foaming direction and limits the position of the foamed adhesive block 4 after foaming.
[0043] Combination Figure 2 It is understood that the foaming limit groove 14 is limited in the upper and lower directions by the upper limit part 13 and the lower limit part 15, and the gap between the upper limit part 13, the lower limit part 15 and the body sheet metal 5 is the gap that the foam block 4 needs to seal. The volume after foaming needs to be filled into the upper gap and the lower gap, and the gap filling of the foam block 4 between the upper limit part 13 and the body sheet metal 5 cannot be higher than the supporting plane 12, otherwise the hot melt adhesive on the supporting plane 12 cannot effectively fill and seal the unfilled gap of the foam block 4 after foaming; therefore, by designing the upper gap of the upper limit part 13 from the body sheet metal 5 to be smaller than the lower gap of the lower limit part 15 from the body sheet metal 5, the length of the upper limit part 13 protruding to the body sheet metal 5 is greater than the length of the lower limit part 15 protruding to the body sheet metal 5, so that when the foaming foam block 4 contacts the upper limit part 13, it is limited by the upper limit part 13. , and the lower gap reserved by the lower limit part 15 is larger, so the foaming will be blocked by the upper limit part 13 and will preferentially foam between the lower gaps of the lower limit part 15. In this way, through structural adjustment, the foaming is filled and overflows downward to the bottom of the lower limit part 15, thereby ensuring the sealing effect of the low point of the vehicle body sheet metal 5; and the foaming is blocked by the upper limit part 13, and can only foam along the upper limit part 13 first, and then foam upward when it reaches the upper gap, thus delaying the filling volume of the gap between the upper limit part 13 and the vehicle body sheet metal 5, thereby avoiding the risk of the upper boundary of the foaming exceeding the supporting plane 12, and providing time and structural support for the sealing of the upper glue.
[0044] In some embodiments, Figure 1 and Figure 2 As shown, the volume of the foam block 4 before foaming is c, and the volume of the foamed filling area is d, d is 5c-8c, unit is mm 3 The volume of the foamed rubber block 4 after foaming needs to fill the foamed filling area to achieve the reliability of the first sealing structure 6. The volume of the foamed filling area is as follows: Figure 1As shown, the volume of the foamed filling area is calculated as a rectangular parallelepiped, and the volume of the foamed filling in the upper gap and the lower gap is ignored. This is because the widths of the upper gap and the lower gap are very small, only a few millimeters, and the thickness of the skeleton 1 is only 1 to 2 millimeters. The volume here can be ignored and has no effect on the choice of the foaming multiple.
[0045] In some embodiments, Figure 1 and Figure 2 As shown, the foam block 4 is arranged on the lower limit portion 15, the height h2 of the foam block 4 is ≥5.0mm, and there is a foaming space between the foam block 4 and the upper limit portion 13. When selecting a material with good foaming effect, there are certain requirements for the height of the prepared foam block 4. If the height of the foam block 4 is too small, it will occupy a larger surface area under the same volume, resulting in an increase in the size of the skeleton 1. Therefore, the volume of the foam block 4 obtained by reasonable height, length and width dimensions can not only ensure the foaming sealing effect, but also reasonably utilize the space and reduce the volume of the skeleton 1; and the reserved foaming space in the foaming limit groove 14 enables the foamed foam block 4 to form a firm bond with the skeleton 1, thereby improving the sealing reliability and stability of the first sealing structure 6.
[0046] In some embodiments, Figure 1 As shown, the frame 1 is a laminated board with a thickness s of 1.5 mm to 2.0 mm. The frame 1 preferably uses a laminated board with good adhesion to foam adhesive and hot melt adhesive to ensure that the formed sealing structure will not crack and fail during long-term use of the vehicle, thereby improving the durability of the sealing structure.
[0047] The material of the frame 1 may also be injection-molded plate, aluminum alloy plate or steel plate.
[0048] As an optional embodiment, a hot melt flowing adhesive block 2 placement area (not shown) is provided above the hot melt sealing area 3 on the skeleton 1 , and the hot melt flowing adhesive block 2 flows toward the hot melt sealing area 3 along the guide slope 11 after melting.
[0049] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0050] Based on the same inventive concept, an embodiment of the present application also provides a vehicle equipped with the above-mentioned vehicle body sealing structure.
[0051] The vehicle provided by the utility model adopts such a double sealing structure between the body metal sheets 5, thereby improving the sealing performance of the entire vehicle, reducing problems such as electrical failures and corrosion caused by the vehicle wading, and improving user satisfaction.
[0052] Based on the double sealing performance of the present application, the sealing structure can be arranged under the A-pillar, under the B-pillar, and at the junction of the C-pillar and the wheel arch where the sealing requirements are relatively high. The sealing is preferably arranged horizontally to facilitate the formation of a second sealing structure 7 with the surrounding components after the high-flow sealant melts.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
